Louise’s answer is not correct. She is missing the term 30x3. When squaring a binomial, it is best to write the product of the binomial times itself. Then you can use the distributive property to multiply each term in the first binomial by each term in the second binomial. Louise also could have used the formula for a perfect square trinomial, which is found by squaring a binomial.

The length of a rectangular prism is four times its width. the volume of the prism is 380 cubic meters. find the length and widt

brilliants [131]

Answer:

The length and width of the prism are 20 metres and 5 metres respectively

Step-by-step explanation: given that the length of a rectangular prism is four times its width. That is

Length L = 4 width W

L = 4W

the volume of the prism is 380 cubic meters

V = L × W × H

380 = 4W × W × H

380 = 4W^2H

W^2H = 380/4

W^2 H = 95

The only way to get a perfect square number is to make H = 3.8

3.8W^2 = 95

W^2 = 95/3.8

W^2 = 25

W = 5

But L = 4W

L = 4 × 5 = 20

The length and width of the prism are therefore 20 metres and 5 metres respectively

Answer:

x = 54

Step-by-step explanation:

Since both triangles are similar, therefore,

$\frac{UV}{PQ} = \frac{VW}{QR}$

$\frac{77}{66} = \frac{63}{x}$

$\frac{7}{6} = \frac{63}{x}$

Cross multiply

$7*x = 63*6$

$7x = 378$

Divide both sides by 7

x = 54
